On failure, fall through to\nout_free instead.","modified":"2026-10-25T02:47:32.126943735Z","published":"2026-10-23T12:19:30.482Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98962.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/578ef517142420cf9d36b364ad4b3490b85469fb"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7a3addbdc5ad1fd80541a6a4ff4e06cd1331530a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a8ea92830b3e0e163d4e829bdcb17ca83c0f951c"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98962.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98962"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"34310c442e175f286b4c06ab5caa4e0b267ea31c"},{"fixed":"7a3addbdc5ad1fd80541a6a4ff4e06cd1331530a"},{"fixed":"578ef517142420cf9d36b364ad4b3490b85469fb"},{"fixed":"a8ea92830b3e0e163d4e829bdcb17ca83c0f951c"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-98962.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.57"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.11"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-98962.json"}}],"schema_version":"1.9.2"}
